I will be watching this thread. There are numerous places within two miles of my house that makes a street legal trials bike very worthwhile. The only street legal one that I know of in California would be the Honda TLR 200.

Anyone know any models that are (or were) street legal trials bikes in Canada/US? Older bikes are ok. I don't need to be competitive on the trails. Just having fun.

The Montesa 4RT was not street legal from the box, but in England they were delivered with lights and signals. Nearly everyone takes that stuff off and many end up on eBay for cheap. My Monty came with a full set of lights purchased in England for less than 100 pounds. I haven't installed them (yet) but I have them. I still need DOT Tires before I go for a title, which is relatively easy in Colorado.

There are a few of these in the country this year,but I'd bet you'd need to decide real soon if you want one as there won't be many.I'm sure it will be up to the owners to see if they can register them in their particular states. I am considering one,but won't have the extra money for awhile.

Arizona is great. I got street legal plate upgrade on my 2012 Sherco 2.9 above the standard offroad plate for $4.75
Didn't even inspect it.
Registered as "primarly offroad" but with street legal status. Not truely street legal as it lacks horn, tail light, mirror. But the biggie is taken care of, registration and insurance. If anyone really wanted to bust me about it I will have a few fix-it items that I will have to address. Not that I will run roads around town with it, but it is legalish on forest service roads and the like now.
